"UFOs are one of the world's greatest mysteries...and I hope they stay that way. For the day that aliens reveal themselves may very well become the beginning of the end of life on Earth as we know it!" A flying saucer crashes deep in the mountains of Japan. Wary of the hyper-intelligent beings they find inside, the government hides from the public all news of the alien craft. But it's not the strange visitors themselves that they should be afraid of--the real danger is the parasitic spores smuggled aboard! Will Earth survive the UFO MUSHROOM INVASION?! Originally published in 1976, Shirakawa Marina's UFO MUSHROOM INVASION is a masterpiece of sci-fi horror. Drawing on his deep knowledge of Japanese folklore and the supernatural, Shirakawa created one of manga history's cult classics and an unforgettably creepy entry in the canon of spore-horror. With an essay by weirdologist Udagawa Takeo, UFO MUSHROOM INVASION is the second volume of SMUDGE, a line of vintage horror, occult, and dark fantasy manga, curated and translated by award-winning historian Ryan Holmberg.
